4 speed 4 door

Haven't seen much discussion on putting a four-speed in a four-door but I imagine it would be the same process as a two-door? I have a 74 Valiant with a 408 Stroker motor that I'd like to put a four-speed behind. From what I've read, non overdrive would be what I want with the iron case. Any specific years or part numbers to look for? I saw there was a couple different bellhousings but couldn't figure out if they all worked or not. Any help would be much appreciated. Also does the floor pan transmission hump fit the same on a four-door as a two-door? If somebody has a full Dropout kit from a donor car that they're looking to sell I would be interested.
